Radiopharmaceutical preparation of technetium-99m-labeled galactosyl neoglycoalbumin

The principal safety features of an injectable solution are sterility and apyrogenicity. A sterile solution does not contain living organisms; an apyrogenic solution does not contain metabolic products of living organisms or debris of dead organisms which can cause a pyretic response on injection. In humans the pyretic response illicits a sudden onset of chills and fever. The chapter describes a method for the laboratory-scale production of an injectable solution of a radiolabeled neoglycoalbumin. This method is applicable to any radiolabeled macromolecule and is directed toward the academic setting where moderate amounts of injectable material are required for testing “proof-of-principle” or a clinical hypothesis.
